Overview

Appearance

There are no physical changes between this state and a regular Super Saiyan Blue form other than the absence of their aura while in the mastered state.

Usage and power

Goku contains the overflowing power of Super Saiyan Blue within himself

Similar to a regular, unrefined Super Saiyan, a Super Saiyan Blue possesses inherently poor stamina. Because of this, a Super Saiyan Blue would usually be able to maintain peak levels of ability for only the brief period following their initial transformation before exhaustion sets in and performance begins to plummet rapidly. Goku addressed this issue by thoroughly training and improving his Super Saiyan Blue form to build up his endurance. As a result of this training, he developed the technique of containing and harnessing his radiating aura inside his body through intense, continuous concentration and uses it to bolster his power. With this method, Goku had achieved mastery over the form, allowing him to realize the full potential of Super Saiyan Blue. In essence, this is a state where the Super Saiyan Blue operates at maximum power indefinitely, making it vastly superior to the basic Super Saiyan Blue.

In many aspects, this state is similar to a Super Saiyan Full Power in regards to the fact that they are refined versions of a normal form. However, similar to the Ultra-full-power Saiyan 4 state, a Completed Super Saiyan Blue requires time and focus to achieve. There is even more skill involved in maintaining this state, as the Saiyan must be capable of prolonged periods of intense mental and physical concentration in order to continuously contain the influx of ki within their body. Inability to do so results in an immediate eruption of ki in even the smallest areas, followed by equally immediate and acute pain. As indicated by Vegeta, this state is a high-risk, high-rewards technique as a Saiyan risks crippling their body if their ki erupts completely.

As stated before, this state is incredibly powerful. In this state, Goku was powerful enough to challenge Fused Zamasu by himself. Concentrating all of his available power to his hand, Goku was able to perform the Destruction technique. Though not nearly as effective as Beerus', this feat still demonstrates the potential of a Completed Super Saiyan Blue.

Vegeta containing the overflowing power of Super Saiyan Blue within himself

Vegeta eventually achieves this state soon after, prior to the Tournament of Power Saga. Beerus notes that Vegeta has grown much stronger and decides to challenge him after the Oracle Fish says that one day Goku and Vegeta will rival him. After Beerus easily knocks around Super Saiyan Blue Vegeta, Vegeta reveals that he, too, can use this form, closing the gap between him and Goku once more. Vegeta is able to land a successful blow on Beerus; however, this infuriates the God, who gets serious and defeats the Saiyan in a single blow. Despite this, Beerus passively acknowledges Vegeta's strength and remarks that he's strong enough to be a candidate for God of Destruction in another universe.

Goku later uses this against Toppo when the latter challenged him. This form proved to be a great match against Toppo's Aura of a God form. However, once Toppo got serious, he easily knocked Goku down, though it should be noted that Goku greatly underestimated him.
